Definitions
- the present invention relates to a method and system for setting up a communication link in a communication network from a communication terminal to a destination communication terminal, in which the communication link is allocated a weighting, and an already existing old communication link to the destination communication terminal is interrupted and the communication link from the communication terminal to the destination communication terminal is set up if the communication link has a higher weighting than the old communication link.
- “setting up” a communication link is understood as meaning both setting up the communication link and continuing (operating, maintaining) the communication link.
- GSM 02.67 Digital cellular telecommunications system (Phase 2+); enhanced Multi-Level Precedence and Pre-emption service (eMLPP)—Stage 1 (GSM 02.67)” Version 5.0.1 of July 1996 from the organization ETSI (European Telecommunications Standards Institute), particularly from page 12, sections 5.8 and 5.9.
- ETSI European Telecommunications Standards Institute
- weightings are given to communication links (calls). Communication links having a relatively high weighting (priority levels) can interrupt existing calls having a lower weighting.
- This method eMLPP is used in mobile radio networks.
- the present invention is directed toward specifying a method and a system which are used to improve the setting up of weighted communication links.
- the present invention includes the feature that, in a method of the aforementioned type, while the communication link is being set up, the weighting thereof is changed by the network if the communication link needs to be set up with lower priority or with higher priority with respect to the first-allocated weighting.
- a particular advantage is that the weighting of the communication link can be changed even if it is not until after the weighting has been allocated; for example, that it is detected that the communication link needs to be set up with higher priority or with lower priority.
- the inventive method can be configured such that a destination address for the communication link is used to detect whether the communication link needs to be set up with lower priority or with higher priority. This is advantageous because it easily can be detected from the destination address for the communication link whether the communication link needs to be set up with lower priority or with higher priority.
- communication links having distinguished destination addresses may need to be set up with higher priority and communication links having other distinguished destination addresses may need to be set up with lower priority.
- the inventive method also can be configured such that the weighting of the communication link is increased if the communication link needs to be set up with higher priority. Increasing the weighting allows the communication link to be set up with higher priority.
- the inventive method also can be configured such that the weighting of the communication link is reduced if the communication link needs to be set up with lower priority. Reducing the weighting of the communication link allows this communication link to be set up with lower priority, so that any already existing communication links can be terminated without being influenced.
- the inventive method also can be configured such that a destination address, appearing in a number plan for the communication network, for the communication link is used to detect whether the communication link needs to be set up with lower priority or with higher priority.
- a particular advantage is that—since, in such number plans, arbitrary destination addresses may be part of communication links which need to be set up with higher priority, for example—the weighting of communication links can be changed on the basis of their allocation when these number plans are used.
- Such number plans can be, for example, “private number plans” which are typically used in companies for the purpose of communication suited to the company structure.
- the inventive method also can be configured such that the weighting of the communication link is increased if the communication link is detected to be an emergency call. This allows emergency calls to be set up particularly quickly, since any existing old communication links can be interrupted in the event of an emergency call arising.
- the inventive method also can be configured such that an intelligent node of a communication network having a structure of an Intelligent Network (IN) detects whether the communication link needs to be set up with lower priority or with higher priority.
- intelligent networks can be used to produce, relatively quickly and easily, services such as the inventive method which extend the functionality of communication networks.
- the inventive method also can be configured such that the change to the weighting is notified by the intelligent node to a service switching point of the communication network using an extended INAP message “Connect”.
- An advantage in this case, is that the change to the weighting can be notified merely by extending the “Connect” message, and no additional new message need be used.
- a system for carrying out the inventive method has detection capabilities for detecting whether a communication link needs to be set up with lower priority or with higher priority, and changing capabilities for changing the weighting of the communication link.
- This inventive system has the particular advantage that when the system detects a lower-priority status or a higher-priority status of the communication link, the system can change the weighting of the communication link.
- the inventive system also can be configured such that the detection part detects from a destination address for the communication link whether the communication link needs to be set up with lower priority or with higher priority.
- a particular advantage is that the lower-priority status or higher-priority status of a communication link often can be easily detected from the destination address if distinguished destination addresses have had a lower-priority status or a higher-priority status allocated to them.
- the inventive system also can be configured such that the detection part has an intelligent node of a communication network having a structure of an Intelligent Network (IN).
- Intelligent nodes in intelligent networks advantageously can be used as detection parts because they can be quickly and easily matched to different tasks.
- the inventive system also can be configured such that the changing part has an intelligent node of a communication network having a structure of an Intelligent Network (IN).
- the intelligent node already used as the detection part advantageously may be used as the changing part.
- the inventive system may have, likewise as the changing part, a service switching point of the communication network.
- FIG. 1 shows, as an exemplary embodiment of the present invention, a detail from a communication network having a communication terminal and a destination communication terminal.
- FIG. 2 shows, as another exemplary embodiment of the present invention, a detail from a cable-connected communication network having a communication terminal and a destination communication terminal.
- the communication network KN shown as a detail in FIG. 1 is a radio communication network (mobile radio network) in the exemplary embodiment.
- a communication terminal MS-A has a maximum weighting assigned to it at least intermittently. If a communication link is set up (a call is set up) from this communication terminal MS-A, the communication link is allocated a weighting which is lower than or the same as the maximum weighting.
- the communication terminal MS-A which is shown by a mobile telephone in the exemplary embodiment, dials a destination address “438”, which is valid within a private number plan, for example.
- a private number plan is used in companies, for example, which set up and catalog their destination addresses (e.g., their telephone numbers) on the basis of rules valid within the company.
- Such private number plans exist for railway companies or police organizations, for example.
- Table 1 shows a detail from a telephone number plan used by European railways, for example, as part of the “GSM-Railway” system. This table shows that the destination address “438” is an emergency telephone number (“Railway Emergency Calls”).
- Table 2 shows, as a detail, an exemplary embodiment of allocations of weightings (“Priority level”) to various communication link types (cf. the aforementioned standard “GSM 02.67” p. 10).
- the weightings 4 to 0 are allocated for communication links by users of the eMLPP method, where the weighting 4 has the least weight (the lowest priority) and the weighting 0 has the greatest weight (the highest priority). In this example, the weighting 0 is used for emergency communication links (“TS12 Emergency calls”).
- a message N 1 is sent in a known manner to a mobile switching center MSC using a radio transmission link.
- the communication terminal MS-A has had a maximum weighting of level 3 allocated to it. Accordingly, the communication link (the call) originating from the communication terminal MS-A is allocated a weighting of level 3 which, in this illustrative case, corresponds to the level of the maximum weighting.
- the message N 1 is used to transmit the weighting 3 and the destination address, among other things, to the mobile switching center MSC.
- the mobile switching center MSC then sends a message IAM to a service switching point SSP.
- the message IAM (“Initial Address Message”) contains, among other things, the dialed destination address “438” as “called number” parameter (“CldNo”) and the weighting “3” as “MLPP” parameter.
- the service switching point SSP detects from the destination address “CldNo” that this communication link is an emergency call, because the destination address “438” has had an emergency call function assigned to it in the private number plan.
- the service switching point SSP then sends an “InitialDP” (Initial Detection Point) message to an intelligent node SCP.
- the “InitialDP” message and the “Connect” message are described, by way of example, in the printed document “ETS 300 374-1 Intelligent Network (IN); Intelligent Network Capability Set 1 (CS 1); Core Intelligent Network Application Protocol (INAP); Part 1: Protocol specification” of September 1994 from the organization “ETSI”.
- the “InitialDP” message contains the destination address “438” as “CldNo” parameter; it can also contain the weighting “3” (not shown in FIG. 1).
- the intelligent node SCP reads, for example from a database (not shown in FIG. 1), which communication terminal has been allocated to the emergency call destination address “438” at the relevant time. In this example, the emergency destination address “438” has an associated mobile communication terminal MS-B having a destination address “123456789”.
- the emergency destination address “438” naturally also can have an associated mobile communication terminal MS-B having a destination address “438”; in this case, the destination address would not change.
- a destination address which is difficult to memorize for a communication terminal (“123456789”) a destination address which is easier to memorize (“438”) for emergency calls.
- the intelligent node SCP after allocation of the destination address “123456789”, the intelligent node SCP returns a “Connect” message to the service switching point SSP.
- This “Connect” message contains the destination address “123456789” of the destination communication terminal MS-B as “CldNo” parameter. Since the intelligent node SCP has detected that the communication link is an emergency call, this connection is allocated the high weighting “0” so that the connection can be set up with higher priority.
- the “Connect” message therefore, contains the weighting “0” as further additional parameter “MLPP”.
- the service switching point SSP After reception of the “Connect” message, the service switching point SSP then overwrites the content of the “CldNo” parameter in the message IAM received from the mobile switching center MSC with the destination address “123456789” of the destination communication terminal MS-B. It likewise overwrites the content of the MLPP parameter with the weighting “0”.
- the altered message IAM′ is then sent by the service switching point SSP to the second mobile switching center MSC2. From this second switching center MSC2, the communication link is set up to the destination communication terminal MS-B in a known manner using a radio channel. If, at this time, there already is an existing old communication link from another communication terminal (not shown in FIG.
- FIG. 1 shows a detail from a mobile communication network as an exemplary embodiment.
- the present inventive method and system are not limited to mobile communication networks, however. Cable-connected communication networks also may be used.
- FIG. 2 shows a detail from a cable-connected communication network.
- a switching center EWSD is arranged instead of the mobile switching center MSC, and a second switching center EWSD2 is arranged instead of the second mobile switching center MSC2.
- cable-connected communication terminals T-A (Telephone A) and T-B (Telephone B) are used.
- the method corresponds to the method illustrated in connection with FIG. 1 and the system corresponds to the system illustrated in FIG. 1.
- the chosen weightings (“Priority level”) should be understood merely as examples; they also may assume values other than those in the exemplary embodiments.
